| (54) | Graphical display of engine cylinder parameters |
| (57) Cylinder engine data, is displayed in a bar chart graphics mode format on a cathode
ray tube (CRT); the data from each cylinder is displayed in dual bar segments comprising
a first bar representing the mean value and a second bar representing the mean deviation
of the measured parameter data, the first bar extending from a zero baseline on the
abscissa to the mean measured value as represented graphically by comparison to a
scaled ordinate, the second bar being generally centered about the first bar mean
value and extending at its end points to the actual peak and actual minimum values
of the selected parameter. |
